Same here! Old blas/lapack/atlas packages just bring confusion, 
especially when unmaintained. Packages depending on 
sci-libs/{blas,lapack,atlas}:
sci-geosciences/grass-5.0.2
sci-chemistry/mpqc-2.2.2

Packages in portage/bugs/overlay which could provide virtual/cblas:
- blas-atlas
- acml (although not sure about this one)
- mkl (at least the one in the overlay)
- cblas-reference
Packages which I know could benefit from it:
- scipy
- itpp

I started to look at the module eselect.blas, to make a few changes. But 
before I go further, it would be nice to know if anyone is working on it 
and if the virtual/cblas is the good direction.

I noticed. A lapack-doc could make sense since it is the same for all 
lapack implementations.

Just rpm2targz'ed the lapack src rpm from
http://download.fedora.redhat.com/pub/fedora/linux/extras/5/SRPMS/
which contains a man pages, quick refs, and a bunch of other patches.
The spec file mentions http://www.netlib.org/lapack/manpages.tgz for the 
man pages. I don't know how Fedora's patches compare to the Gentoo's 
ones, and my last experience on a RH/Fedora computer was 5 years ago.

Cheers,
